HORSESHOE-CALK.

To all whom it may concern:

Be it known that I. J osEPiI A. PENNIXG- roN, a citizen of the United States, residing at Moscow, in the county of Latah and State of Idaho, have invented a new and useful Horseshoe-Calk, of which the following is a specification.

This invention relates to horseshoe calks, one of its objects being to provide a calk which can be used either with or without rubber or a like plastic material. 7

Another object is to provide a calk which provides a firm footing and prevents the horse from slipping in any direction.

A still further object is to provide simple and eiiicient means for attaching the calk to a shoe.

Nith the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the coinination and arrangenient of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings V Figure 1 is a bottom plan View of a horseshoe having the presentimprovements combined therewith;

Fig. 2 is a section on line 2-2, Fig. 1;

Fig. 3 is a section on line 33, Fig. 2;

Fig. 4 is an end elevation of the calk detached; and

Fig. 5 is a top plan view of the calk.

Referring to the figures by characters of reference 1 designates the base portion ofa call: having side walls extending'throughout the length thereof as indicated at 2 and converging toward their free longitudinal edges. In the base 1 near one end 1s provided an. opening 3 while a pin 4 is extended from said base near its other end, this'pin, if desired, being screwed into the. base, as shown particularly in Fig. 2. A longitudinal groove 5 is formed in the base and is intersected by the opening 3 therein.

A block 6 of rubber or other plastic material is arranged between the walls 2 of the body and is held against displacement by frictional engagement with said Walls Specification of Letters Patent. Patented )[a 19, 1918,

from the base 1.

The horseshoe with which'the calk is to be used, and which has been indicated at S, is provided with a pair of apertures 8 and 9 ateach point where a calk is to be 'attached. One of these apertures 9 has its wall threadedand has seated within it the threaded end of a pin 10 which projects downwardly from the shoe and is provided with a diametrical opening 11. The other aperture 8 is of such size as to receive the pin 4 of the calk.

\Vhen it is desired to attach a calk to a shoe, t-he anchoring pin 10 on the shoe is inserted through the opening 3 in the base of the callt, while the holding pin 4 which projects from the call: is inserted into the opening 8 in the shoe. is then driven longitudinally within the groove 5 and will pass into the opening 11, thus securely fastening the calk to the shoe.

It is to be understood that the calks can be applied wherever desired, it being merely necessary to provide the shoe with the openings 8 and 9 and the pins 10 at the point of attachment. 7

One or more of the calks can be formed at each end with angular wings or spurs 13 integral with the calk and which will operate to prevent lateral slipping. Obvi ously the block 6 can be dispensed with if desired.

In Fig. 1 the toe 'calk has been shown provided with spurs 13, while the side calks are not formed with these spurs; It is to be understood that spurs may be arranged on the side calks or, if preferred, they may be dispensed with on all. of the calks.

Having thus described the invention, what is claimed as new is:

1. The combination with a shoe having an opening therein and an anchoring pin extending from the shoe and adjacent the opening, of a call: including a base having an opening for the reception of said anchoring pin. a pin projecting from the base and insertible into the opening in the shoe, a locking pin extending longitudinally of the'base and through the anchoring pin projecting from the shoe, and a block of plastic material connected tothe base.

2. The combination with a shoe having an opening therein and an anchoring pin adjacent the opening, of a calk including A locking pin 12.

s and also by a series ofscrews 7 or other a base hating an oenirfg Ha-6m for the reception of the anc ioring pin on the shoe5 a holding pin extendi g frornthe b ase for insertion into the opening on the shoe, a locking pin extending along the base and through the anchoring pin extending from PheA QeZ Q YQbY 20 hold h base shoe, Walls along the sides of the base and converging outwardly thetefrofn, a plastic material housed between the Walls and seture in the presence of two Witnesses.
